Changing packaging version

[hjoaquim]

This PR patch the deprectation of LegacyVersion under packaging - also discussed here: pypa/packaging#631

• Removes LegacyVersion
• Specifies that packaging=">=22.0"

Steps taken:

poetry add packaging=">=22.0"
poetry export -f requirements.txt  -o requirements.txt --without-hashes --dev
poetry export -f requirements.txt  -o requirements-full.txt --extras prediction --extras optimization --without-hashes --dev

Fix:

• [Bug] new release of pypa/packaging might break openbb  #3750

I think the better solution will be to change:

current_version: Union[version.LegacyVersion, version.Version]

to

current_version: version.Version

And then add packaging^22.

Thoughts?

Does the Tests / General Linting create a fresh environment each time? The error does not make sense since version.parse() returns only Version with packaging 22

It uses the actions/cache@v3 to restore dependencies. I am not sure how to change those, so you may need to just add packaging==22 to the yml

It creates a fresh env when the dep tree is re-solved

The tests create a new env, but the linting uses the cache from gh actions. That has not been updated in 9 months.

I used this doc to open a new PR that will edit the cache when the poetry lock changes: https://docs.github.com/en/actions/using-workflows/caching-dependencies-to-speed-up-workflows
